As much as I might want to see the scientists' definition of human including them as apes, it seems clear to me that humans do not hang and swing by natural incination from trees. I think monkeys and gorillas do that. But right now i'm going to stop there -- except to say that the so-called "Unknown Common Ancestor" just has not been determined. I won't even go into Lucy now because I don't know that much about it, like if they think she did not swing from trees. So all these branches or species(?) stemming from that Common Ancestor...unknown what, and when.
Now I'm beginning to wonder how many initial "common ancestors" there were, and at what point did they break out into the various sectors. The fact that similarities may be there does not mean that humans came about by natural selection. Yes, I believe they are far different from humans.
Since I believe in the Bible and feel it comes from a higher source of intelligence, I will say that just like elephants' brains are not human brains, neither are gorillas' brains like human brains. I think that's about it for now, again I thank you, you are making me think about it and I appreciate that, I know I don't know everything about the Bible's explanation and I won't go any further with that now as contrasting to the ToE for the most part. Except to say that elephants' brains are different than human brains and same for gorillas and monkeys. I can understand the process of evolution. In contrast, however, the Bible offers me an explanation I do not overturn or bury. So if I meet Moses someday, I hope to find out how he knew these things since he was not alive when the earth was created and life began.
